Zero-degree focusing of channeled ions and crystal rainbows
(Physics Letters A, 2001)
We analyze here theoretically the connection between the effect of zero-degree focusing of channeled ions and the crystal rainbow effect. The calculations were performed for Ne10+ ions and a LT 100 GT Si thin crystal. The ...
Rainbows with a tilted 〈111〉 Si very thin crystal
(Physics Letters A, 2002)
The angular distributions of protons channeled in a tilted (111) Si very thin crystal together with the corresponding rainbow patterns are considered. The proton energy is 10 MeV while the crystal thickness is 121.1 nm, ...
Proton channeling through long chiral carbon nanotubes: The rainbow route to equilibration
(Physics Letters A, 2008)
In this work we investigate the rainbows appearing in channeling of 1 GeV protons through the long (11, 9) single-wall carbon nanotubes. The nanotube length is varied from 10 to 500 pm. The angular distributions of channeled ...
Influence of the dynamic polarization effect on the angular distributions of protons channeled in double-wall carbon nanotubes
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2007)
We investigate the influence of the effect of dynamic polarization of the carbon atom valence electrons on the angular distributions of protons channeled in (6, 4)"(11, 9) double-wall carbon nanotubes. The proton velocities ...
Crystal rainbows
(Journal of Electron Spectroscopy and Related Phenomena, 2003)
This review is devoted to ion transmission through axial channels of thin crystals. In this process the rainbows occur. The effect is called the crystal rainbow effect. We shall describe its origin and present the experiments ...
Doughnuts with a 〈110〉 very thin Si crystal
(Journal of Electron Spectroscopy and Related Phenomena, 2003)
This study is devoted to the angular distributions and transmission patterns of 10 MeV protons channeled in a tilted LT 110 GT very thin Si crystal of thickness 100 nm. The tilt angle of the crystal is varied from zero up ...
Rainbow effect in channeling of high energy protons in (10,0) single-wall carbon nanotubes
(Materials Science Forum, 2005)
We investigate theoretically the angular distributions and the rainbows of 1 GeV protons channeled in the ropes of (10, 0) single-wall carbon nanotubes. The rope length is varied between 0.53 and 5.29 mu m. The angular ...
On the doughnut effect and the rainbow proton-silicon interaction potential
(Advanced Ceramics and Applications, 2021)
This work shows how recent experimental results of angular distributions of 2 MeV protons channeled in a 55-nm-thick (001) silicon crystal tilted away from the [001] direction can be explained by the very accurate rainbow ...
